Abstract

Un ritardatore idrodinamico (7) viene azionato nella presa di moto da un albero condotto (1) di un cambio di velocità ad ingranaggi tramite una trasmissione (8, 9) a ruote cilindriche con rapporto di trasmissione in salita, laddove l'albero condotto (1) tramite un cuscinetto a rotolamento (11) è supportato in un coperchio di supporto (12) avvitato con una scatola-cambio (10). Una unità del ritardatore idrodinamico (7), costituita di rotore (15) e statore (14), è disposta in una scatola (13) del ritardatore. Per realizzare una modalità costruttiva compatta del dispositivo, costituito di cambio di velocità ad ingranaggi e ritardatore (7), conservando un diametro possibilmente grande dello statore (14) e del rotore (15) nonché un rapporto di trasmissione in salita possibilmente grande perA hydrodynamic retarder (7) is actuated in the power take-off by a driven shaft (1) of a gear gearbox via a cylindrical wheel transmission (8, 9) with an upward gear ratio, where the driven shaft ( 1) through a rolling bearing (11) it is supported in a support cover (12) screwed with a gearbox (10). A hydrodynamic retarder unit (7), consisting of rotor (15) and stator (14), is arranged in a retarder box (13). To achieve a compact construction mode of the device, consisting of gear speed change and retarder (7), maintaining a possibly large diameter of the stator (14) and of the rotor (15) as well as a possibly large upward gear ratio for
